I use Evohome to control my central heating remotely, and very good it is too.

Worth a look: here.
Yes, that does look very interesting. I have very little experience with smart heating control systems (beyond rewiring a Nest Heat Link that the heating engineer had connected incorrectly) but that looks to be a much better in terms of controlling multiple zones. Thank you.


I had Evohome in my previous home for just over 4 years. It is a great system when it works but like all Zigbee systems it can suffer from communications issues between the various components. It’s USP for your situation is its built in failsafe protocols. For example, if an eTRV loses contact with the main controller it will start a cycle of calling for heat: similarly, with the BDRs. With this system it should be almost impossible to get frozen pipes. That said, the person managing the system does need to have some knowledge of how the system works. It is not FIT and FORGET.

I also recommend EvoHome, it's very flexible in terms of heating control though I wish Honeywell also provided wireless room thermostats that weren't TRVs, as my wife took one look at the EvoHome wireless TRVs on the radiators and decided she hated them and wanted them removed, so now the only benefit I get from EvoHome is a WiFi controllable on/off switch for the central heating.


Is it the size of TRV's or display? If it's the display, can't you refit them with display facing wall?

Aren't TRV's fit, set and forget.

It’s a fair comment. The reason that I haven’t fitted Evohome in my present home is simply because most smart systems are not age friendly. I am in my 70s, and if my wife was left on her own she wouldn’t have a clue how to, for example, change the batteries in a HR92. I got a call a couple of years after I sold my Evohome house with a request for help. The purchaser had an issue with the heating not coming on, and he had pressed system RESET. He couldn’t find a heating engineer that knew enough about Evohome to help him out. It took me a couple of hours on the phone to talk him through the various set up and re-binding processes. Double binding of components is Evohome’s Achilles Heel.

It's the display (which isn't on unless you press the hidden menu button) and the fact that "a display on a radiator valve is ridiculous, I'm not having it!", regardless of whether it could be seen frown

You could put a cover over so they can't be seen.

Over you wife, that is.

Thanks Sarah; That is just what I wanted to hear, especially "If you have guest policies enabled for the public network on the Unifi access points, folks who connect to that won't be able to see your heating controllers."

The current heating control system is three domestic type 7-day programmers in a box which are sort of easy enough to program, but checking through the whole week is a pain.

I get 30-minute gas consumptions the following day from SSE and end up wondering just why the heating for the main hall was on overnight on a Sunday etc! Especially as the boiler can consume 60 kWh of gas in the first 30 minutes on a cold morning...

Thanks again.

Cheers!

Clive - Don't know if you've made any progress of the remote CH setup at the village hall, but I'd recommend you have a look at the Tado system. I'd previously run Nest (since pre Google buyout) but Tado (despite some idiosyncrasies is on the whole a very good and very flexible setup.

Nothing fitted as yet, but following our AGM on Wednesday, it was agreed to obtain a quote from a specialist company who is involved with Building Management Systems.

If it was a normal Village Hall type building it would be quite easy, but with a mixed use of Village Hall and rented out Office space, needs to have ability to be controlled by the Office Tenants as they come and go during the week, but at the same time keeping inquiring fingers away from the programming selection, plus of course the means for the building Manager and myself to access remotely.

Cheers!

No worries, a proper commercial spec BMS will of course be fine, but wont necessarily come in cheaply.

Tado and the ilk can get combinations of both wired, wireless temperature sensors/stats, vertical and horizontal TRV replacement heads, extensions etc for quite modest outlay, something like £180 for a starter kit: including a wired or wireless room stat/sensor, CH/HW wiring centre interface and internet bridge.

Extra wired temperature senders/room stats are around £110 and the wireless versions are £70. Depending on the granularity of heating control you desire, individual Tado TRV's are about £60. The app is free, and pretty easy to understand navigate.

I have a 7 independent zone CH system setup at home, controlled via Tado. Tado will control up to 25 devices/heating zones.

I thought Tado was 10 zones, have they increased the number?

I swapped from Evohome to Tado. I think Evohome is getting a bit long in the tooth now. I could never get Evohome to work properly as there was clearly some form of interference (or software bug that they were not admitting) but non of the technical people could say for certain what the problem was. This led to the boiler being fired even when there was no demand, or other scenarios where all TRV's were closed, yet controller showed a demand from some of the TRV's.

I still get some gremilines with the Tado (and Tado don't really seem to listen to their community who recommend obvious improvements that should just be), but I certainly prefer the usability of Tado of Evohome. For people with a Valllant boiler the Tado can do eBUS so modulates, where as the Evohome ends up just turning boiler on and off all the time.
